Lending their famous faces to a good cause, Colin Farrell and Katharine McPhee showed up at the Elizabeth Taylor AIDS Foundation Art Auction Benefit in Los Angeles last night (February 27).

The “American Idol” alum treated the crowds at the Wilding Cran Gallery to some silky smooth vocals while rich people bought paintings for charity.

In related news, Farrell, who was a very close friend to Taylor before she died, told the reporters that he was a nervous nelly the first time he met Liz.

"I had less anxiety waiting for the results of a home pregnancy test. And that's the truth, that's not just a cheap joke. That's the truth."

"[Her manager] was there, he opened the door, he said, 'Come on in. She should be down in a minute.' And seconds turned into minutes and minutes turned back to seconds. I was very, very nervous, and I waited for an hour, but Dame Elizabeth … only she could be socially late at her own house. An hour passed and she came out, and we sat and we spoke and I laughed and I had the most bewitching hour of my life, and I left on a cloud."
